问题 In WP7 I am used to generating sample data (XML) from my ViewModels in Blend and seeing them in Visual Studio. In Blend 2012 I cannot find the option to generate design time data. The tempales in Visual Studio use design time data genarated in code. Is it the only way? No more XML design time data? 回答1: I don't think generating design time data in Blend for VS2012 is possible, but it's still possible to use design time data created in code, but even this is more complicated than in WP7.

So the problem is with the following two lines: const CLSID CLSID_MMDeviceEnumerator = __uuidof(MMDeviceEnumerator); const IID IID

问题 Stream stream = await new HttpClient().GetStreamAsync( url ); How can i create a file in app's local folder having data downloaded through this stream as file content? 回答1: You could probably do some kind of stream to stream copy. However, I happen to just use the response object in my code: var client = new HttpClient(); var response = await client.GetAsync(uri); if (response.IsSuccessStatusCode) { Stream stream = null; StorageFolder localFolder = ApplicationData.Current.TemporaryFolder;

问题 How can I implement removing the backStack Entry in Metro style applications? 回答1: frame.SetNavigationState("1,0"); will clear the navigation history for you. 回答2: I found this answer useful: How to clear Backstack of the frame and start afresh Write your own NavigationService and store the navigationstate in the constructor. string state; public NavigationService(Frame mainFrame) { state = mainFrame.GetNavigationState(); _mainFrame = mainFrame; _mainFrame.Navigating += _mainFrame_Navigating;

Basically, I need something similar to what is shown as an example here: http://msdn.microsoft.com/en-us/library/system.io.driveinfo.aspx 回答1: Remember that metro style applications are severely restricted in the parts of the operating system they can access. I don't believe that it is possible for a metro style app to scan arbitrary

问题 I am working on an app which displays videos and am running into an issue where the machine goes to sleep after hitting the sleep time limit while a video is playing. Is there a way to disable this behavior in a Windows 8 Metro application? 回答1: You should use the DisplayRequest class, specifically DisplayRequest.RequestActive for this purpose.

问题 I have a date string coming from JSON "2012-08-01T15:42:06Z" and want to parse that in Windows Runtime. As far as I know, only COleDateTime is available to handle this. I can only get it to correctly parse the string when I take out the 'T' & 'Z' characters, but that adds an extra parsing step on my end.
